Jika 404 dilaporkan, terdapat masalah dengan halaman, web.xml, fail konfigurasi spring mvc dan Pengawal


1. / ditukar kepada /*

2 Lihat kod Pengawal dan semak sama ada paparan yang dikembalikan adalah betul dan sama ada ia boleh sepadan dengan halaman jsp

.
伊谢尔伦

<url-pattern>/</url-pattern> akan memadankan URL jenis laluan seperti /login, tetapi tidak akan sepadan dengan URL jenis akhiran seperti *.jsp

<url-pattern>/</url-pattern> akan sepadan dengan semua URL: URL jenis laluan dan jenis akhiran (termasuk /login, .jsp, #🎜🎜 #.js dan .html, dsb.)

<servlet-name>SpringMVC</servlet-name>

<url-pattern>/</url-pattern>

Tiada masalah dengan konfigurasi poster asal. Tidak perlu menukar / kepada /*.

Peter_Zhu

Sila siarkan konfigurasi @RequestMapping pengawal.
